HF Band analysis using JT65-HF-HB9HQX

I use JT65-HF-HB9HQX for JT65 for on all bands from HF to 6m. A great feature when displaying the "Band Statistics" window shows a number of useful items:

  • QSOs - shows the total number of contacts per band and a total for all bands
  • Stations - shows the total number of unique stations contacted per band and a total for all bands
  • Grids - shows the total grid squares worked per band and a total for all bands
  • DXCCs - shows the total number of DXCC entities worked per band and a total for all bands

Antenna erected and working

The antenna is an end fed dipole (essentially a long wire of 20m with a 9:1 UNUN). I bought this from Martin Lynch Ltd in the UK and it is sold as their Mydel 80-6m end fed dipole (see here).
I also decided to invest in some decent coaxial cable and connectors so bought 25m of Messi and Paoloni Flex 7 cable and their matching Messi and Paoloni PL259 connectors. These are unlike any coax connector I have ever seen before.

The connector part that looks like a top hat slides onto the copper foil covered inner conductor and slides in between the cable sleeve and copper outer sheath. The black piece is actually rubber and the clamping gland compresses this and is supposed to make a hermetic seal. I used some self amalgamating tape over the entire assembly.

Waiting for the postman

I ordered a load of antenna parts from Amazon the other day to aid erection of my new HF dipole. Everything has come apart from 10 off 3mm shackles and 5 off 6mm Stainless Steel Cable Clip Saddle Clamps. These are essential to clamp the guy lines in the air.

I looked on Amazon today, they have been despatched but have a delivery estimate: Monday, 23 March 2015 - Wednesday, 15 April 2015 despite them being ordered 12th March 2015.

Why does it take so long for delivery? Most other items arrived within a couple of days.
